I like how thorough and topic related your interviews were. It seemed that because of your interviewees proximity to kid’s snacking that you got better insights that you would have if your interviewees were more separated from the topic.
I wish you had gone into more depth with your “experience” section. I know that you eat them, but what is the experience like, and how could you connect it to our topic. Develop it further.
What if to further understand the experience of the nanny, you, on several occasions, packed meals/snacks for you or others? This could help to understand issues and user experience associated with school lunches and snacking on the go.
